FRIEDRICH AUS DER MARK, OF STERKRADE, GERlVIANY.

LEVELING APPARATUS FOR HORIZONTAL COKE-OVENS.

To all whom it may concern:

Be it known-that- I, FRIEDRICH are one MARK, a subject of the German Emperor, residing at Sterkrade, Rheinland in Germany. have invented a certain new anduse= :tul Leveling Apparatus for Horizontal Coke-()vens, of which the followingis a.

place at each reversal. The present inven-- tion obviates this ditticulty by means of a simple and reliable device, which consists in using a rope attached at the middle to the bar and led to the right and left over rollers carried by the frame. and from the e rollers to two drums or pulleys loosely and indeiendently mounted on the driving axle, the rope hein; led to the top ol one drum and the 'ittoin ot' the other. By alternately clutching the two drums, by means of a clltt'tli between them. the desired reciprocation of the bar is produced. The reversal of the clutch is either performed n'ianually by the motor-1min. or automatically by the bar, during the levelinf Two torms oi o struction are shown in the accompanying drawing. Ht which Figures 1 and 2 diagrannnnt ically represent an apparatus wherein the two pulleys or drums are. both on one shat", with the clutch between them. Figs. 7, and -'lshow siniilar apparatus. with the ditl'erence that the polleys are sitlt' -l) \-sitle, on parallel shafts and are alternately clutched. Fig. 5 illustrates the application ot the invention to an electrically actuated as a coke'expelling n'iar-hine- Fig. (3 is a detail of part ol the reversing mechai'iism.

The tootl'iliiss bar 1/, guided by the rollers I). 7).. w. (Z, has the rope f, f attached to it at c. The part of the rope. passing over the roller Z1 at the oven-side ot the frame. is acniacl'rine which also serves' Specification of Letters Patent.

tuatcd by the drum g: the part f passing over the roller I) on the oft-side, is actuated by the drum 72 The two drums g and h are loose on the shaft i, which revolves continuously in the direction indicated by the arrow. ll'hen the clutch la is operated by the lever l to clutch the drum g the bar (I pulled by the rope f, moves into the coking; chamber. the rope 7' being unwound from the drum 7:. \Vhen the drum /1 is clutched the bar move in the opposite direction. lly this means not only the insertion. and with drawal are ell'ected. but the action of the clutch fl' causes the bar to be moved during the trinnning operation. After bar a. has been properly introduced into the oven. it is automatically reciprocated by the following means: Lever Z, is secured to a vertical shaft which carries at its top a crank Z provided at its free end with a displaceable pin 7". The latter is arranged in the path of a pair of stops m, projecting laterally from bar a. When introducing the bar into the oven. pin This swung downward to clear stop in. After the bar has been so far advanced that pin Z. has arrived intermediate stops m, said pin is returned to its original position. whereupon the device is started. Steps on, by engaging pin Z will tilt crank 7 so as to intern'iit'tently oscillate lever 7.

and thus alternately couple drums y. and 71.

to shatt i. Tn this way the direction of travel of rope f. is reversed when bar arrives at its terminal positions. as will be readily understoot'l.

l claim:

A leveling apparatus for horizontal coke ovens. comprising a leveling bar. a driving shaft journaled below said bar. drums loosely mounted on said shaft. a clutch arranged between the drums. a gear rope attached to the ar and wound around the drums in opposite directions. a reversible clutch-lever. a pair of stops on the leveling bar. and a pin pivoted to the lever and being adapted to be swung into or out of the paths oti said stops.
